Vaginal bleeding during female pregnancy is related to factors such as preeclampsia, ectopic pregnancy and embryonic arrest, which need to be analyzed specifically.
1. Pre-eclampsia: If the chromosome of the embryo is abnormal or subjected to other interfering factors, the fetus will be prone to growth disorders and pre-eclampsia, and the shedding of the gestational sac tissue will cause abnormal uterine bleeding.
2. Ectopic pregnancy: if the fertilized egg is not in the endometrium but in other parts of the uterus such as fallopian tube, it is easy to cause local tissue rupture and vaginal bleeding.
3. Embryonic arrest: If the fetus dies in the uterus, it can also cause abnormal vaginal bleeding due to the shedding of tissue from the gestational sac.
Bleeding from below when you are pregnant may also be related to other factors. If such abnormal bleeding occurs, you need to go to the hospital in time for blood HCG (human chorionic gonadotropin) measurement to determine the growth and development status of the fetus.
